Narrated by:Anas bin Malik said
It was narrated that Anas bin Malik said:"I was with the Messenger of Allah on a journey, and he said: 'Is there any water?' He performed ablution and wiped over his leather socks, then he joined the army and led them (in prayer)."
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا عُمَرُ بْنُ عُبَيْدٍ الطَّنَافِسِيُّ، حَدَّثَنَا عُمَرُ بْنُ الْمُثَنَّى، عَنْ عَطَاءٍ الْخُرَاسَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنْتُ مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فِي سَفَرٍ فَقَالَ " هَلْ مِنْ مَاءٍ " . فَتَوَضَّأَ وَمَسَحَ عَلَى خُفَّيْهِ ثُمَّ لَحِقَ بِالْجَيْشِ فَأَمَّهُمْ .
